Klump

Klump API

The Klump REST API lets a merchant verify transactions, sync commerce product catalogs, create Klump Access hosted payment pages, and resend webhooks. A single base URL serves both sandbox and production; the environment is selected by whether the merchant application state is TEST or LIVE and by which secret key is presented. Every request must carry the merchant secret key in a klump-secret-key header; the public key (klp_pk_ prefix) is used client side with the Klump.js widget.
